Leners Patent No. 86,675, daad February 9, '1869.

IIVEPROVEDFEED-REG-ULATOR POR BARE-MILLS.

The Schedule referred tn in these Letten Patent and making 'pm of the name.

To all whom it may concern Be it known that I, BENJAMIN IRVING, o; the city, county, and State of N ew York, have invented certain new and useful Improvements in Apparatus for Regulating or Distributing the Feed of Crushed `Bark to` blue outlines show the belts for connecting the various parts of the machine together, andthe red outlines, the main gearing-wheel, the same letters of reference, wherever they occur, referringto like parts.

Letter A is the jrame of the machine, on the front end of which is arranged a series of three crusher! rollers, B, C, and D, geared together by cog-wheels E,

F, and G, as described in myprevious vinvention cfa Underneath these rollers is arranged, between the side-rails of the frame, a, water-bath, H, in which are arranged paddle or agitator-wheels I, for the purpose of stirring up the iibrous mass of bark falling into the bath from the Crusher-rollers, and at the same tim carrying it back to and upon an elevator, J.

This elevator' is formed as an endless belt, running under a roller, K, in the bottom of the water-bath, and

up over a roller, L, secured between posts M, projecting up from the side-rails of the iame, near its back end,` and has Yo n it a series of wire-gauze buckets.

By this means, the mass of brous' crushed barkw is taken from the water-bath, and discharged upon and between a series ofthree-tallor compresser-rollers, N,

P, and Q, geared together by cog-wheels R, S, and T, 1

and, by means of belts U, connected with the front series of rollers, to rotate simultaneously with them, and

thus extract or compress the liquor from the mass of bark as fast as made and delivered to them.

Io'` feed the pulpy mass of bark into and between the tail or compresser-rollers, it is made -to fall from the elevatorbuckets upon a feed-distributer plate, V, (shown in yellow outline,') secured to a rock-shaft, W, arranged between 'the posts M of the frame, and having its lower edge constantly resting upon the lperiph-- ery of the back lower .roller P, of the seriesof tailn vrollers. y

To vibrate the rock-shaft, a lever, X, is attached to one end of it, and by means of a connecting-rod, Y, attached to a crank-pin, Z, on the end of the upper elevator-roller shaft, having a less diameter or throw than that of the lever X, its rotation vibrates the rockshaft W, and thus keeps .the distributer-plate V constantly in motion, to shovel, as it were, the pnlpy mass of bark in between the rollers.-

It will be obvious, from the nature of the material, that, if discharged upon a fixed or stationary trough, it would soon lodge, and choke up, or would, at other times, accumulate in too great quantities at one time between the rollers, to have them compress the extract out thoroughly, even if` it did not have the effect of breakingthe rollers down by over-work.

By my invention, the object is to distribute the feed evenly and constantly over the surface and between the' rollers as fast as it falls from the elevator-buckets, and thus automatically keep up the continuous operations of the entire machine.

Having now described my invention, I will proceed to set forth` what I claim, anddesir'e to secure by Letters Patent of the United States.

I claim the combination of the feed-distributer plate V with the rock-shaft W, lever X, and rod Y, all arranged substantially as described and for the purposes hereinbefore set forthl 1 v Witnesses: BENJAMIN IHIVING.
